Portfolio and Limited Company Landlords in Wales

Four or more mortgaged buy-to-let properties is the point the Bank of England's Prudential Regulation Authority calls you a "portfolio landlord" — triggering whole-portfolio affordability checks from any regulated mortgage lender, personally, jointly, or through a limited company (PRA, Supervisory Statement SS13/16, effective 30/09/2017). Below that line, most landlords manage compliance property by property without much strain. Above it, the arithmetic changes — not because Rent Smart Wales charges more per property, but because every additional dwelling adds its own EICR renewal, gas safety anniversary, deposit deadline and arrears risk, all running in parallel.

This guide covers what genuinely changes for portfolio and limited-company landlords in South Wales: licensing costs, HMOs across multiple properties, ending contracts at scale, and where a limited company fits — without straying into tax advice, which needs an accountant.

What counts as a "portfolio landlord" in Wales?

There's no Welsh-law definition — it's a mortgage-industry term. The PRA sets the threshold at four or more mortgaged buy-to-let properties, triggering enhanced underwriting from regulated lenders regardless of how the properties are held (PRA, Supervisory Statement SS13/16). Rent Smart Wales doesn't use this threshold — its obligations attach to you as a landlord no matter how many properties you own, covered below. Four properties also happens to be where our own management-fee conversation moves from a fixed number to a bespoke one — more further down.

Does Rent Smart Wales licensing get more expensive as your portfolio grows?

No — not in fees. Registration and the landlord licence are both flat, one-off charges per landlord under Rent Smart Wales's fee policy (effective 1 April 2025), not per property. What scales with portfolio size is the compliance workload sitting behind each property, not the paperwork bill.

Cost item	Self-managing landlord	Using a licensed agent
RSW registration (every 5 years)	£60 online / £102 standard — per landlord, not per property	Same — registration is still required either way
Landlord licence + training course	£254 online / £327 standard, plus a training course — per landlord, every 5 years	Not needed — the agent's own licence covers all letting and management activity
Per-property compliance tracking (EICR, gas safety, deposit deadlines, written statements)	Your own responsibility, multiplied across every property you own	Tracked for every property under management
Management fee	N/A — you're doing it yourself	Flat 10% + VAT

Self-manage and you also need a training course alongside the licence. Use a Rent Smart Wales–licensed agent for all letting and management activity instead, and you skip the licence and training entirely — the agent's own licence covers it. See our full Rent Smart Wales guide for the registration process step by step.

Figures current under Rent Smart Wales's fee policy effective April 2025. Rent Smart Wales reserves the right to revise fees, so check rentsmart.gov.wales before budgeting a renewal.

Does the compliance workload really multiply with more properties?

Yes. Every property carries its own five-yearly EICR (given to the contract-holder within 7 days of occupation), its own annual gas safety check, its own deposit-protection deadline (within 30 days), its own smoke/CO alarms, and its own EPC of band E or above to be let (Minimum Energy Efficiency Standards, in force since 1 April 2020). With one property, missing a deadline is a single mistake; with ten, it's ten clocks running at once — and just one lapse (an expired EICR, an unprotected deposit, an unlicensed HMO) can block your ability to serve a valid section 173 no-fault notice on that specific property, exactly when you might need to recover it. EPC C by 1 October 2030 is confirmed government policy, not yet law (Rent Smart Wales, following the Warm Homes Plan announcement of 21/01/2026) — if it lands as expected, a ten-property portfolio means ten separate upgrade decisions.

What about HMOs across a bigger portfolio?

Each HMO is assessed and licensed individually — there's no portfolio-wide HMO licence. A property needs a mandatory HMO licence if it has three or more storeys, five or more occupants, forming two or more separate households — all three conditions together (Licensing of Houses in Multiple Occupation (Prescribed Descriptions) (Wales) Order 2006). Some councils also run additional licensing schemes covering HMOs below that threshold; Cardiff Council, for example, runs one in the Cathays and Plasnewydd wards. Rules vary by council, so check each property's local authority rather than assume one regime covers a whole portfolio.

If HMOs are part of your mix, we manage those separately from standard lets — treating an HMO like a single-let is where problems usually start. See our HMO regulations guide for the detail.

Should I hold a Welsh rental portfolio through a limited company?

That's a tax and structuring question for an accountant, not a letting agent, and we won't advise on it here. What stays the same either way: Rent Smart Wales obligations apply to a company landlord exactly as an individual, because the legal definition of "landlord" includes a body corporate. A limited company (commonly a special purpose vehicle, or SPV) is registered at Companies House regardless of where the property sits.

One genuinely Wales-specific point: property purchases in Wales pay Land Transaction Tax (LTT), not Stamp Duty Land Tax, administered by the Welsh Revenue Authority since April 2018. Buying an additional residential property, including through a company, attracts higher LTT rates; these changed on 11 December 2024, so don't rely on a figure quoted elsewhere — check the current rate on the Welsh Revenue Authority's own LTT calculator before budgeting a purchase. For corporation tax, mortgage interest relief or whether incorporation suits you, speak to an accountant who knows property.

What changes day to day when you're managing several properties, not one?

The legal deadlines don't change per property, but the odds of one slipping rise with every property you add, and possession law is unforgiving of a slip, whether you've got one property or fifteen.

Get an arrears case wrong and it costs months. Serious rent arrears on a monthly periodic standard contract is defined in law as at least two months' unpaid rent (Renting Homes (Wales) Act 2016, s.181) — there's no cash figure anywhere in the legislation, so don't rely on anyone telling you a fixed amount like "£200 a month" is the legal threshold; it isn't. The notice is served under section 182 (periodic) or section 188 (fixed-term), using Form RHW20, and a claim can't be made within 14 days of serving it, or after 6 months from it — get the section wrong and you risk starting again, expensive when running several arrears cases at once. Our arrears guide covers the process step by step.

Recovering several properties at once — restructuring, selling up, refinancing — means planning around the no-fault route (section 173): a minimum of six months' notice, set by section 174, unusable in a property's first six months, and blocked entirely if any compliance item is outstanding on that specific property. Exiting a ten-property portfolio means ten separate six-month clocks, not one. See our section 173 notice guide for the timing.

What does portfolio management cost with Morgan Jones?

Our management fee is a flat 10% + VAT, whatever the size of your portfolio — we don't publish a tiered percentage table that gets cheaper as you add properties. For four properties or more, we talk about a bespoke rate directly, because at that scale the right conversation is about your specific mix of properties, not a fixed number on a table.

Switch to us and every property you bring across gets three months' free management, the same offer we give any landlord moving agents — it simply adds up faster across a portfolio. Get a quote for your properties and we'll talk through what a bespoke portfolio rate looks like.

Frequently Asked Questions About Portfolio and Limited Company Landlords

Can I mix limited-company and personally-held properties in one portfolio?

Structurally, yes — obligations attach to whoever holds each property, personally or through the company, because the legal definition of "landlord" includes a body corporate. Whether it's the right approach for your tax position needs an accountant, not a letting agent.

Does Wales cap how big a security deposit I can take?

No — unlike England's five-week cap, there's currently no statutory limit on a security deposit in Wales (the Renting Homes (Fees etc.) (Wales) Act 2019 leaves room for a future cap by regulations, but none has ever been made). Don't confuse this with the holding deposit, which is capped at one week's rent. See our deposit protection guide for the detail.

Does an HMO in my portfolio need its own licence even if my other properties don't?

Yes. HMO licensing is assessed property by property against the mandatory threshold and any council-specific additional scheme — it isn't portfolio-wide, and one property's licence doesn't cover another.

What happens if I switch agents partway through a portfolio?

We handle each property's transition separately — contacting the current agent, arranging handover, and notifying that property's contract-holders — so it doesn't need to happen for the whole portfolio on the same day.

Managing this at scale

Self-managing a portfolio, or mixing HMOs in with standard lets, multiplies the decisions above rather than changing them.
